The U.S. Supreme Court on Monday required Arizona to continue to issue driver’s licenses to the young adult immigrants known as Dreamers, refusing to hear the state’s challenge to an Obama-era program that protects hundreds of thousands of people brought into the country illegally as children.

The case centred on the Deferred Action for Childhood Arrivals (DACA) program created in 2012 under Democratic former President Barack Obama that Republican President Donald Trump already has sought to rescind. Those who signed up for DACA are shielded from deportation and given work permits.

The high court refused to hear Republican-governed Arizona’s appeal of a lower court ruling that barred the state from denying driver’s licenses to people protected under DACA.

Mark Brnovich, Arizona’s Republican attorney general, expressed disappointment that the justices sidestepped the issue of whether Obama had the authority to create DACA.

Police departments have been sending their leaders to Israel to learn about the country's counterterrorism strategies since the 1990s. But growing opposition is pushing some to rethink these exchange programs.
